BOATS.

Patented Oct. 21, 1919.

Application filed February 11, 1918. Serial No. 216,642.

To all whom it may concern Be it known that I, HARRY W BROADY, a citizenof the United States, and residing at Bayside, in the county of New Yorkand State of New York, have invented a new and Improved Engaging andDisengaging Gear for Ships Boats, of which the following specificationis a full disclosure.

This invention relates to improvements in engaging and disengaging gearfor ships boats.

By the use of my invention, I am enabled to produce an engaging anddisengaging gear which may be released under a load or when the boat isbeing water-borne or towed; and which will be so'arranged that all theparts of the device readjust themselves automatically for engaging sosoon power is taken 0d the pull-chain and at the same time will lock thehook against movement when the gear reaches its engaging position so asto prevent releasing accidentally through any agency other than thepullchain. Furthermore, the said gear is so arranged that it will beimpossible to lock or stick either in fully released position or in anyother intermediate position.

Another feature of my invention enables the ring of the falls, when thedevice is in engaging position to be freely moved inwardly intoengagement with the hook but will, without special manipulation, preventoutward movement of such ring to disengage the same while the hook is insuch engaging position and said gear will furthermore automatioally freethe ring from such restraint when the devicereaches'its releasingposition.

To these ends I provide in combination with a pivoted andcounterweighted tripping hook which is suitably supported, apower-multiplying device or system of levers, preferably pivotallymounted adjacent to the hook and connected thereto in such manner thatwhen the counter weight swings the hook into engaging position it willalso cause the lever parts of the device to be automatically moved intoposition to form a toggle joint and thus through their connection withthe hook lock the same in such engaging position against movement by anyother agency than through a suitable pullchain secured to such lever.Preferably the hook and counter weight are formed in two as the strainor parts and the counter weight is pivoted to the hook so that anymovement thereof will cause the hook to be swung around its pivot fromengaging to disengaging positions and vice versa. Furthermore, the leverparts are so arranged that one of them forms a continuation or shank ofthe hook and when such levers are actuated the hook will be caused tohave a closing and opening move ment in relation to said shank part orlever so that the ring of the falls may be more readily freed when theparts are in releasing position. As illustrated, the pivotedtripping-hook has pivoted to it, what I shall term, a shank-leverprovided with a suitable counter weight which shank lever forms acontinuation Or shank of the hook and this shank lever furthermore hasintegrally formed therewith a rearward extension which has a pivotalconnection with a link which is, in turn, pivoted to the supportingbracket adjacent to the hook pivot, the parts being arranged in suchrelationship that when the hook is in engaging position the pivotalconnection first between the shank lever and hook and second, betweenthe rear ward extension and the link, and, third, between link andsupporting bracket, will be in alinemcnt and produce a togglelockingjoint which will lock the hook against accidental movement in itsengaging position and furthermore, these parts of the gear are soarranged that the said rearward extension will abut against the linkpivot or a suitable hub thereon to limit its movement to engagingposition and will abut against the hook pivot or a suitable hub thereonwhen it is moved to its extreme releasing position, in which position.the parts areprevented from looking.

When it is desired to provide an automatic ring-retaining device incombination with the gear. I preferably provide a pawl which is weightedwith the counter weight and pivoted to the shank lever and so arrangedas to move pivotally on the said shank lever a limited distance againstthe action of the said weight in one direction only so as to permit theringto be moved through the mouth of the hook or through the spacebetween the shank lever and the end of the hook in one direction but toprevent or stop any movement in the opposite direction so that when thering is once in place it will be retained beneath the hook until thetogglelever joint hereinabove described has been broken and the hookmoved to releasing position, in which position the relative dispositionof the hook and shank lever will be such as to completely free the mouthof the hook and to permit the exit of the ring therefrom.

Other objects will be in part obvious from the annexed drawing and inpart indicated in connection therewith by the following analysis of thisinvention.

This invention accordingly also consists in the features .ofconstruction, combination of part and in the unique relations of themembers and in the relative proportioning and disposition thereof, allas more completely outlined herein and in said drawings.

To enable others skilled in the art so fully to comprehend theunderlying features that they may embody the same by numerousmodifications in structure and relationship of parts contemplated bythis invention, drawings depicting a preferred form have been annexed asa part .of this disclosure, and in such drawings like characters ofreference denote corresponding parts throughout all the views, of which:

Figure 1 is a lan view of a boat embodying an installation of myimproved engaging and disengaging gear.

F ig. 7 is a front elevation, partly in section, of the gear shown inFig. 5,

Fig. 8 isanother side elevation of amodified form of my inventionembodying a ringretaining pawl; V

Fig. 9 is a similar side elevation showing the gear in releasedposition;

Fig. 10 is a section on the line 10-10 of Fig. 8; and

Fig. 11 is a'section on. the line 1111 of Fig. 8.

Referring nowto these drawings, 1 indicates a boat and 2 the, keelthereof. To the keel at opposite ends of the boat 1 are, as shown,mounted my improved disengaginggears, the gears at opposite ends beingconnected by pull-chains 3 to a common releasing handle 4. v

The engaging and disengaging gear which forms the subject matter of thisinvention, embodies, as shown, a hook 5 which is mounted on a fixedpivot 6 in a bracket 7 suitably secured by rivet or other fasteningdevices 8 to the keel 2 of the boat 1. To the rear end of the hook 5. ispivoted at 9*, what I Shall term, a shank lever 9 which, as shown inFigs. 1 to 7, is provided integrally with a counter weight 10 and has arearwardly extending arm 11 which is pivoted at 12 to link 13 which, inturn, is pivoted at it to the bracket 7 The parts are so arranged thatwhen the gear is in the engaging position shown in full lines in Figs. 2and 5, the pivots at 9 12 and let will be in alinement with each otherand a toggle-joint will be produced whereby the hook will be lockedagainst movement except through the agency of the pull-chains 3 and theparts will automatically swing into position to form this toggle-jointthrough th action of the counter weight 10. As illustrated, the rearwardextension 11 of the shank lever 9 is bifurcated, and when the gear isinengaging and locked position, the edge 11 of such eXten slOll will abutagainst the hub 13 ofthe link 14 so as to limit the rearward movement ofthe parts. lVhen the parts are, by a pull upon the chain 3, swung intoreleasing position as illustrated in dotted lines in Fig. 2, the saidrearward extension, as shown particularly in Figs. 2 and 8, will abutagainst the hub 5? of the hook 5, as hown at 11 in Figs. 2 and 9,whereby the forward movement of the parts is limited and the device isprevented from locking in its disengaging position. In Figs. 5, 6 and 7I have illustrated an installation of my gear supported by one of thethwarts 15 which is slotted as at 16 and provided with a supportingbracket 17, the installation being reinforced by reinforcing strips 18which are mounted on the pivot'6 at one end and secured to doublebracket 19 at the opposite end which is, in turn, connected to the keel2 of the boat. These supporting strips have attached thereto, a rearwardextension 20 in which the link 13 is pivoted. The supporting strips '19also support a pulley-block 21, the pulleyblock 21 having a pulley 21around which the chain 3 is adapted to be led. In other respects theinstallation is the same as that illustrated in Figs. 1 to 4.

In Figs. 8 to 11 I have illustrated a form of gear which is in allrespects similar to the gear shown in Figs. 1 to i inclusive except thatthe shank lever instead of being pro vided with an integral counterweight is bifurcated at 9 and has pivoted thereto at 22.

a pawl 23 which has integrally formed therewith the counter weight 10.The pawl 23 is so arranged in relation to the shank lever '9 that it isfree to move in one direction as illustrated in dotted lines in Fig. 8against the action stopped from moving in the opposite direction bycotiperating abutinents 9 and 23 on the shank lever 9 and pawl 2-3,respectively. Obviously, a ring such as indicated in dotted of theweight 10 but is lines at 24 may be passed upwardly between the shanklever 9 and the end of the hook 5 by simply pressing the ringagainst thesaid pawl when thecounter weight 10 will be swung on its pivot to permitthe entrance of such ring. So soon, however, as the ring passes the pawlthe weight will automatically assume the position shown in full lines inFig. 8 and the ring will thereupon be locked in position beneath thehook and above the pawl so that it will be impossible to release thesame (without specially manipulating the weight) during the time thegear is in its engaging position. however, the shank lever and weightare swung forwardly by the pull-chain 3 the hook will be swung around onits pivot in such relationship to the said shank lever 9 as to free themouth of the hook and permit the ring to move freely therefrom. So soonas the pull is relieved from chain 3, however, the weight 10 will causethe parts to resume the initial position shown in Fig. 8 and the pawl 23will again assume its mouth-blocking position.

The operation of the device will be obvious from the foregoingdescription.

I claim:

1. The combination with a pivoted, counterweighted tripping hook andmeans for supporting the same, of power-increasing levers having apivotal connection with the hook and a pivotal connection with asuitable support adjacent to the said hook, and means for actuating oneof such levers to swing the hook 011 its pivot from engaging todisengaging position.
